Passive Band-Pass Filter Calculator

This is a first-order, single pole, passive RC band pass filter calculator composed of two RC filters, a high pass followed by a low pass. Set the desired cutoff frequency to generate resistor and capacitor values, then adjust the bode plot max frequency to view the response over the desired frequency sweep.

A technical schematic for a 6-channel Passive Wideband Pass Filter. The page features six identical active filter circuits arranged in two columns, labeled VIN1 through VIN6. Each circuit utilizes an RC circuit with varying capacitor and resistor values to achieve specific -3dB cutoff frequencies ranging from 1 Hz to 10 MHz.
